I am currently 22. 214@15% 6'1"

I am thinking of doing

Weeks 1-6 Dbol 60mg daily
Weeks1-12 test ent 250mg e3d
Weeks 13-14 nothing
Weeks 15-18 nova (tamoxifen) at 40mg/40/20/20

I know this isn't a super crazy cycle as its gonna be my first.
What should I expect from a cycle like this? Is doing Dbol and test together for a first cycle too much?

How much of what I gain should I expect to keep while not on anything.
